What we do

The Office of Sustainability (OOS) works with partners around the City to improve quality of life in all Philadelphia neighborhoods, reduce the City’s carbon emissions, and prepare Philadelphia for a hotter, wetter future.

OOS is responsible for implementing Greenworks Philadelphia, the City’s comprehensive sustainability plan, which is made up of eight visions:

  • Accessible food and drinking water
  • Healthy outdoor and indoor air
  • Clean and efficient energy
  • Climate-prepared and carbon-neutral communities
  • Quality natural resources
  • Accessible, affordable, and safe transportation
  • Zero Waste
  • Engaged students, stewards, and workers
